Answer:
see attachments
Step-by-step explanation:
The side lengths are found using the distance formula.
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of RS in the first triangle is ...
d = √((4-(-1))^2 +(4-(-3))^2) = √(25 +49) = √74 ≈ 8.602
This same computation is used for all of the sides of the triangles. When the same tedious computation is repeated over and over, I like to use a spreadsheet to do it. In the attached spreadsheet the two points used are the one on the same line as the distance, and the one on the line below. Side lengths are shown in the attachment to 3 decimal places.
__
In order to classify the triangle as acute, right, or obtuse, we can compare the side lengths to those of a right triangle. For the purposes of computation in a spreadsheet, it is convenient to compute the middle length side of a right triangle that has the same longest and shortest sides as the triangle we have.
If the computed side is longer than the actual middle side, then the triangle we have is obtuse. If it is shorter, the triangle we have is acute. If it is exactly the same, then the triangle we have is a right triangle.
In every case here, the computed middle side is shorter than the actual middle-length side, so all of the triangles are acute triangles. (The one of problem 39 is isosceles, since two sides are the same length. The others are scalene.)

The triangles are graphed in the second attachment.

Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
Answers
9514 1404 393
Answer:
$91.56
Step-by-step explanation:
We can simplify Nancy's cost expression to ...
c +0.09c = c(1 +0.09) = 1.09c
The the total cost of the item of interest is ...
(1.09)($84) = $91.56

1/2 (18t) +2t(9)-12
Answers
Answer:
The answer is 27t - 12.
Step-by-step explanation:
1) Remove parentheses.
[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]
2) Use this rule: a/b × c/d = ac/bd.
[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]
3) Simplify 1 × 18t to 18t.
[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]
4) Simplify 18t/2 to 9t.
[tex]9t + 2t \times 9 - 12[/tex]
5) Simplify 2t × 9 to 18t.
[tex]9t + 18t - 12[/tex]
6) Collect like terms.
[tex](9t + 18t) - 12[/tex]
7) Simplify.
[tex]27t - 12[/tex]
Thus, the answer is 27t - 12.

About 0.6 of all the students in the fifth grade are girls. If the fifth grade has 85 students, how many of the students are girls?
Answers
Answer:
51 girls
Step-by-step explanation:
85 represents the total amount of students in 5th grade, including boys and girls.
0.6 or 60% of the 85 students in 5th grade are girls.
0.6 x 85 = 51
Therefore, there are 51 girls out of the 85 students in 5th grade.
The diagram shows a wedge ABCDEF.
The base of the wedge is a horizontal rectangle measuring 60cm x 40cm
Answers
9514 1404 393
Answer:
77.3 cm
Step-by-step explanation:
The distance FA is the diagonal of rectangle ABFE. We know the length AB, so we need to find the length BF. That is found using the trig relation ...
cos(25°) = BC/BF
BF = BC/cos(25°) ≈ (60 cm)/0.906308 ≈ 66.203 cm
Then the diagonal length FA is found using the Pythagorean theorem:
FA = √(AB² +BF²)
FA = √(40² +66.203²) ≈ √5982.79 ≈ 77.349 . . . cm
The diagonal length FA is about 77.3 cm.

solve 17+6p=9
pls explain
Answers
6p=9-17
6p= -8
p= -8/6
p=-4/3
First we want any number with p on one side and all the other numbers on the opposite side. So we’ll subtract 17 from both sides of the equation.
6p = -8
Then we need to divide both sides by 6 to find p
p = -8/6
Most teachers want the fraction reduced, so it would be -4/3 or - 1 1/3

Log10 (2x + 1) - logio(3x - 2) = 1
Answers
Answer: x=3/4
Step-by-step explanation:
To solve, first express the left side as one logarithm. To do so, apply the quotient rule which is log_bM/N=log_bM-log_bN .
log((2x+1)/(3x-2))=1
Then, express the equation to its equivalent exponential form to eliminate the logarithm.
Note that the exponential form of log_b M=a is M=b^a .
Since the base of the logarithm in the given equation is not written, it indicates that its base is 10.
So re-writing the equation, it becomes:
log_10((2x+1)/(3x-2))=1
And its exponential form is:
(2x+1)/(3x-2)=10^1
(2x+1)/(3x-2)=10
Now that the equation has no more logarithm, the next step is to remove the x in the denominator.
To do so, multiply both sides by 3x-2.
(3x-2)*(2x+1)/(3x-2)=10*(3x-2)
2x+1=30x-20
Next, combine like terms.
To combine 30x and 2x, bring them together on one side of the equation. So, move 2x to the right side by subtracting both sides by 2x.
2x-2x+1=30x-2x-20
1=28x-20
To combine 20 and 1, bring them together on the side opposite the term with x. So, add both sides by 20.
1+20=28x-20+20
21=28x
And, divide both sides by 28 to have x only at the right side.
21/28=(28x)/28
3/4=x
Hence, the solution to the given equation is x=3/4 .
